BURLINGTON, Vt. — A woman has pleaded guilty to a charge that she intentionally crashed her car on Vermont’s Interstate 89 in Richmond killing another driver.

In exchange for the plea, prosecutors Thursday dropped a second-degree murder charge and other charges that had been pending against 25-year-old Karri Benoir, of Barre.

Benoir pleaded guilty to a charge of gross negligent driving. Sentencing will come at a later date, but the deal calls for Benoir to serve six-to-15 years in prison.

Prosecutors have said they believe Benoir was attempting to kill herself when her car crossed the median in July 2015 and hit a car driven by Brendon Cousino, of Richmond, nearly head-on. Benoir’s attorney has disputed that assertion.

Benoir has been jailed while her case was pending.
